I want to make a https request.
I use bouncycastle to generate the keystore like this :
keytool -importcert -trustcacerts -alias ludevCA -file lu_de
Have a Look on it Android: Trusting SSL certificates
-storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath /path/to/bouncycastle.jar
And use this version when creating your keystore: Version 1.46 found here
May it Helps...
